"That's a real problem. It's affecting every aspect of human life here in Gaza."

He added that the situation was deteriorating every day, with waste, water supply and transport problems endemic.

"Now the estimate is that 60,000 litres [of raw sewage] per day is being pumped into the sea simply because there is no fuel to run the plant that's needed to treat that sewage," he told Al Jazeera.

'Dire situation'

The agency resumed distributing aid in the besieged Palestinian territory only last Tuesday after a four-day interruption also caused by fuel shortages.

Mike Hanna, Al Jazeera's correspondent in Gaza, had said that the fuel crisis was, "a very dire situation indeed. Seen in a wider context, this is just one issue that is plaguing Gazans every single day."

Cars in Gaza, lacking fuel, have largely begun using a mixture of petrol and cooking oil.

Hanna said: "The dangers of this are obviously its going to shorten the life of the engines, but also, these are time bombs on the road. At any stage, one of them could explode, creating great loss of life.
